The thyroid gland is regulated by a negative feedback loop. ... Here's how thyroid regulation works. The hypothalamus secretes thyrotropin-releasing hormone, or TRH. TRH stimulates the pituitary gland to produce thyroid-stimulating hormone, or TSH

In the following choices below, the correct answer of which
corresponds to the statement of a highly contagious food borne illness that
results from biological contaminants is letter a, salmonella. The salmonella
are pathogens that are intracellular. The infection occurs because of the
contamination of food with feces.
1. it <span>supports muscles and tissue
2.it also </span><span>protects the vital organs
3. </span>The skeleton gives the body its shape, which changes with growth. In
addition to determining characteristics such as height and the size of
the hands and feet, stable body shape enables essential functions. For
example, a stable rib cage and spine enable the lungs to fully inflate
when breathing. Conditions such as osteoporosis of the spine and broken
ribs can alter the shape of the chest and impair this vital body
function.

5.Larger bones contain bone marrow, a spongy tissue inside the bones.
There are two main types of marrow, red and yellow. Red marrow is
responsible for production of all of the body's red blood cells and many
of its white blood cells. Red blood cells are produced at an average
rate of approximately 200 million per day. These cells carry
life-sustaining oxygen to the body tissues.
In adults, red marrow is found primarily in the breastbone, hips, ribs,
skull, spinal bones and at the end of long bones of the arms and legs.
Several types of white blood cells, which protect the body from
infections, are also produced in red bone marrow. Yellow bone marrow
contains primary fat cells but can transform into red marrow if the body
needs to increase blood cell production, such as if anemia develops
